Christina Redmond & Daniel Arencibia from UH's Our Project in Hawai'i's Intertidal (OPIHI) internship are investigating the intertidal zone of Maunalua Bay.

Christina Redmond's group had the exciting opportunity this past semester to study the rocky intertidal zone of the Western end of Maunalua Bay. They surveyed this site to gather invertebrate and algal species richness, diversity, and density. The overarching goal is that if the patterns of intertidal community composition along these gradients can be predicted, then we may have the ability to track long-term physical changes and characteristics in these organisms that may arise due to climate change and other anthropogenic effects in the future.

Daniel Arencibia's group studied the effects of groundwater on algal communities at Black Point. Relatively few species are observed close to the seep compared to areas further away from the seep suggesting that only specific algae can tolerate the chemical conditions brought in by the groundwater. A nitrogen isotope analysis (used to determine the sources of nutrients) revealed that tolerant algae are taking up these nutrients closer to the seep. Their team plans to continue to investigate how groundwater and other physical and chemical variables influence the algal community at Black Point and the rest of Maunalua Bay.
